Introduction

The Total Lunar Eclipse of -0659 Nov 26 (0660 Nov 26 BCE) is visible from the geographic regions shown on the map to the right. The diagram above the map depicts the Moon's path with respect to Earth's umbral and penumbral shadows. Click on the figure to enlarge it. For an explanation of the features appearing in the figure, see Key to Lunar Eclipse Figures.

The instant of greatest eclipse takes place on -0659 Nov 26 at 00:30:02 TD (19:04:39 UT1). This is 4.0 days before the Moon reaches apogee. During the eclipse, the Moon is in the constellation Gemini. The synodic month in which the eclipse takes place has a Brown Lunation Number of -31924.

The eclipse belongs to Saros 44 and is number 40 of 85 eclipses in the series. All eclipses in this series occur at the Moon’s ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.

This total eclipse is central meaning the Moon’s disk actually passes through the axis of Earth’s umbral shadow. It has an umbral eclipse magnitude of 1.7398, and Gamma has a value of 0.0403. Because they are so deep, such eclipses typically have the longest total phases. In this case, the duration of totality lasts 103.6 minutes. That qualifies the eclipse as a member of a select class of exceptionally long total eclipses with durations exceeding 100 minutes.

The total lunar eclipse of -0659 Nov 26 is preceded two weeks earlier by a partial solar eclipse on -0659 Nov 11, and it is followed two weeks later by a partial solar eclipse on -0659 Dec 11.

These eclipses all take place during a single eclipse season.

The eclipse predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 19522.9 seconds for this eclipse. The uncertainty in ΔT is 491.3 seconds corresponding to a standard error in longitude of the eclipse visibility zones of 2.05°.

At time t1 (decimal hours), each besselian element is evaluated by:

x = x0 + x1*t + x2*t2 + x3*t3 (or x = Σ [xn*tn]; n = 0 to 3)

where: t = t1 - t0 (decimal hours) and t0 = 1.000

Calendar

The Gregorian calendar (also called the Western calendar) is internationally the most widely used civil calendar. It is named for Pope Gregory XIII, who introduced it in 1582. On this website, the Gregorian calendar is used for all calendar dates from 1582 Oct 15 onwards. Before that date, the Julian calendar is used. For more information on this topic, see Calendar Dates.

The Julian calendar does not include the year 0. Thus the year 1 BCE is followed by the year 1 CE (See: BCE/CE Dating Conventions). This is awkward for arithmetic calculations. Years in this catalog are numbered astronomically and include the year 0. Historians should note there is a difference of one year between astronomical dates and BCE dates. Thus, the astronomical year 0 corresponds to 1 BCE, and astronomical year -1 corresponds to 2 BCE, etc..

Eclipse Predictions

Predictions for the Total Lunar Eclipse of -0659 Nov 26 were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. The predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 19522.9 seconds for this eclipse. The uncertainty in ΔT is 491.3 seconds corresponding to a standard error in longitude of the eclipse visibility zones of 2.05°.
